Does anyone know any encoders where I can create an FLV from a thumbnail image (jpeg, png, etc) and an mp3? (So basically, the image stays static while the mp3 plays).
youd have to make it into a movie and then convert it into a .flv good online converter “here http://media-convert.com/":http://media-convert.com/">http://media-convert.com/
Movie Maker, which comes with Windows Xp and Vista, can do it as well. it generates a .wmv but then that can be uploaded to youtube for flv.
or you could just load the image and mp3 into After effects, drag them into a new comp, then render as .flv
